Asequence is defined by the recursive function f(n + 1) = f(n) – 2. if f(1) = 10, what is f(3)? 1 6 8 30

Answer : 6

A sequence is defined by the recursive function f(n + 1) = f(n) – 2.

f(1) = 10, f(3) = ?

Before finding f(3) we need to find f(2) because we are using recursive formula. also f(1) = 10 is given.

f(n + 1) = f(n) – 2, f(1) = 10

f(2) = f(1) - 2  (plug in 10 for f(1))

f(2) = 10 -2 =8, so f(2) =8

f(3) = f(2) -2 = 8 - 2 = 6

So f(3) = 6

The value of f(3) = 6

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
